LVP Programming

Low-Voltage Programming (LVP) can only be used for these PIC devices if the LVP configuration bit is enabled. Fresh (unprogrammed) devices have LVP bit set and therefore they can be programmed. It is impossible to disable LVP bit during LVP programming, but if the device has been previously programmed with HVP programmer, the LVP bit may have been disabled.

When brown-out is enabled with BOREN configuration bit, LVP is only possible when the VDD voltage is above the brown-out threshold.

These limitations may be avoided with High-Voltage Programming (HVP). NSDSP-2 can generate high voltage for HVP internally. NSDSP-1 cannot, therefore NSDSP-1 requires NSHVX or an external circuit for HVP.

HVP Programming

NSDSP-2 can program PIC16F818 with HVP.

With NSDSP-1, HVP programming is possible, but only with NSHVX High Voltage Extension or an external HVP circuit.

Debugging

NSDSP cannot be used to debug PIC16F818.
